Pen



Patented Dec. 14, 1948 UNITED [STATES l:.PATIE'NT ,OFFICE y l Arthur WinterfWeeha'wken, N. J. Application SeptemberZZ, 1944, Serial No. 555,243 Y v.This invention relates to .fountainpens l Anzobject of the inventionis to provide a pen j A further object is to provid-e a feed mechanism..

in: which allowances are made for varying air pressure so that the pen will not leak at lower air pressures. .v

A still further object is to provide a pen in which all of the feed mechanism is protected by the barrel and wherethe'greater portion of the point is covered to protect it from damage.

A still further object is to provide a pen in which a metal feed may be used. The metal feed has certain advantages insomuch as it can be made in iiner and sharper lines, eliminates breakage, and gives a much moreeven flowof ink. While my construction makes possible the usev of a'metal feed my invention is not-limited to such material and a plastic feed may be used therein.

In the accompanying drawings-f- Figure 1 is a plan view'of apen embodying my invention; l

Fig. 9 is a plan view of a pen point designed to be used with my improved feed;

Fig. 10 is a .view of the pen cover; and

Fig. 11 is a modified form of the outer feed.

My pen is provided with a conventional barrel l5 and feed sack I6 adapted to engage cover section I1. The cover section l1 has .a reduced portion I8 to receive the sack and another reduced portion I9 to engage the inner circumference of the barrel. This may be threaded, if desired, or may -be frictionally engaged. The cover l1 is tapered and at the forward end 20 has an opening 2| to allow the passage of the nib 22. The top 23 extends slightly beyond the bottom 24` so that a greater portion of the top of the pen nib is covered than at the bottom portion.

The coverk l1 is adapted to receive kand frictionally hold the outer feed 30 which is formed with a bore 3l extending from the front thereof to the end 32. A portion of th outer feed is cut away 9 claims. (o1. 12o-5o) n `to'forrna ring'33 and an open section 34. The

rear'portion lof the feed is grooved at 35 with a longitudinal grooveextending into the end 32 at 36. Lateral grooves 31 are provided as ink storage spaces as are smaller grooves 38l in the open section. This outer feed may be made of plastic,

' vof hardrubber 4or. plastic. n The plug is formed with two longitudinal grooves4l and 42 merging intoa slot 43 at the forward end 44 of the said plug. Slot-,43 is `vadapted to receive shank 25 of the pen 22. The rear of the shank is cut away `at 26.to lregister with the portion 45 of the plug place and togive it greater support than is possiso as, to rmly xthe position of the pen nib within thesaid plug. When the said plug is made offrnetal the end 44. maymore readily be constructed lto frictionally hold the pen firmly in ble with rubber or other plastic.

`In the .form of outer feed shown in Figure l1 theV Outerieed 50.is formed in much the same manner with the slot 5IA extending from the rear 52 tothe open portion 53. The grooves 31 and 3 8 are eliminated. f When the penis assembled plug 40 is inserted into the outer feed 30 with the grooves 4I and 42 at right angles to the groove 35, as shown in Figure 4. The assembled feed is then fed into the cover with the slot 43 in the same direction as the opening 2l and nib is inserted within the slot 43. The balance of the pen is then put together in the usual manner.

In operation the cuter feed not only tends to position the inner feed and the pen nib but acts to convey ink to the nib. The outer end 33 of the hollow outer feed 30 contacts the edge of the nib 22, as shown particularly in Fig. 2. This steadies the pen nib against sidewise motion and also holds the slotted end of the inner feed snugly against the pen nib. The cutout or open section 34 acts as a safety chamber to take care of any excess ink which may be forced through the rear part of the outer feed by means of pressure in the ink chamber or sack, thus preventing leakage due to varying air pressures.

I claim:

1. In a fountain pen a feed including an outside feed having a bore therein. a portion of said outside feed being cut away to define an open section into said bore. a slot extending into said bore and running from the open section to the rear of the outside feed, a plurality of grooves communicating with said slot, a feed plug posiin said outer feedLsaid-feed plug-havingga pair of grooves running longitudinally thereof and merging short of the forward end of said feed plug, to form a slot, a pen positioned in said slot, and

an outside cap entirely covering said feed mecha- I nism, and Ahaving an aperture for the projection.. MT

of the pen nib therethrough.
